The surfaces of the plates are also corrugated so as to assist in diffusing the light.

In the drawing B, B, are the burners, S an ordinary glass shade for mellowing the light, R the reflector composed of the inclined, corrugated, plates p arranged in octagonal shape and connected by standards a, a, leaving the space between them open for ventilation each series or row of plates being smaller in circumference and graduating toward the top, by this means the light is reflectedand diffused through the room.
